Contributing to the Diagram

They must resolve, with or without content negotiation, to RDF data in one of the popular RDF formats
(RDFa, RDF/XML, Turtle, N-Triples).

The dataset must contain at least 1000 triples. (Hence, your FOAF file most likely does not qualify.)

The dataset must be connected via RDF links to a dataset that is already
in the diagram. This means, either your dataset must use URIs from the other dataset,
or vice versa. We arbitrarily require at least 50 links.

Access of the entire dataset must be possible via RDF crawling, via an RDF dump, or via a SPARQL endpoint.
